Application filed February 18, 1886. Serial No. 192,328. (No model.) I

To all whom it may concern:

Be it known that I, CORNELIUS CALLAHAN, of Chelsea, in the county ofSuffolk and State of Massachusetts, have invented a new and ImprovedHose Pipe and Nozzle 3 and I hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, making part of this specification, in whichFigure 1 is a side elevation of my improved hose pipe and nozzle. Fig. 2is a longitudinal section of the same. Fig. 3'shows the parts separated.Figs. 4, 5, and 6 are details to be referred to;

The object of my invention is to provide a hose-pipewhich may be bent tochange the direction of a stream through an arc of ninety degrees, andyet not have the hose-pipe co'llapse or in any way reduce the diameterof the stream; and my invention has also for its object to provide ahose-pipe with a nozzle which will project a film or sheet of waterwhich shall be interposed between the pipeman and the fire, and protecthim from the heat and smoke.

To this end my invention consists of aflexible hose-pipe provided withthe proper couplings and spirally wound on the outside with a wire inadirection opposite to the thread in the butt-coupling, and the ends ofthe wire fastened in the couplings withthe fabric.

My invention also consists in the details of construction of the nozzle,as will be hereinafter fully described, and specifically pointed.

out in the claims.

In order that those skilled in the art may make and use my invention, Iwill proceed to describe the manner inwhich I have carried it out.

In the said drawings, A is a flexible-fabric hose-pipe, provided, as isusual in such cases, with a nozzle-coupling, B, and a butt-coupling, O.Around the outside of the flexible fabric is spirally wound a wire, a,of brass or other elastic material. This spiral wire is wound in adirection opposite to that of the direction of the thread in thebutt-coupling 0, so that the manipulation of the hose-pipe will not tendto loosen the coils of the wire by any equal to the diameter of the wireused. Thisspacing or location of the coils compensates for the changingof position of the coils as the pipe is bent, the coils separating onthe outside curve as the hose-pipe is bent, and closing up together onthe inside curve. The ends of the coiled wire are secured under each oneof the couplings B and O at the same time that said couplings are fixedpermanently to the fabric.

On the end of the coupling B is secured in the usual manner the reducerD, and this is tapped at its end to receive a removablespraying-section, E, which has an interrupted wall, producing asubstantially circular opening or spraying -outlet, b, the short studs dd supporting the divided wall of the sprayingsection. Interiorly,immediately before the opening or outlet b, the dimension of the pipe iscontracted slightly, as seen at 2. A beveled flange, e, surrounds theopening or sprayingoutlet b, andserves'to give the escaping sheet orfilm of water a direction forward from the pipeman. The section E istapped at 'l, and has a portion of its exterior surface smooth, as seenat t". A movable sleeve, F, threaded exteriorly to fit screw i, movesback and forth on the screw 1; and smooth surface 12, and has at one enda projecting flange, k, into the edge of which is fitted a leatherpacking, I, designed to be screwed down against the flange e, topartially or wholly close the opening I) and cut off to a greater orless extent the spray or film. The opposite end of the sleeve F isprovided with a stuffing-box and packing-ring, n, whereby all leakage isavoided. The extreme end of section E is tapped to receive any desiredform of reducing mechanism, or any appliance that may be found to bedesirable.

will be observed that this sprayer fits on the ral wire woundexteriorly, and havingits ends I with the spraying-section E, havingcircular io clamped beneath and in combination with the outlet 12, andthe moving sleeve F, provided couplings B G, substantially as set forth.with the packing and flange Z k and stufifing- 2.
